To all/whom it may cm'u'crn; i p I Be itkuown that l, Romurr Sinurimzn, a citizen of the United States, and a resident of :Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented ztfncw and useful 1m pro venien t in Support i 11; St ru cturesfor Byiiuirio-Electric Machines, of which the following isnspecilicetion. Mg'invcntion relate-7s to dynamo-electric mac ines and particularly to motors th'etnre mounted upon and directly surround the driving axles of locomotives or other vehie relations have usually to the driving Wheels; the niotors thus zip-' plied being, in gencrel, ad's tcdyfor slower speeds of operation than -t e more usual forms that areconnec'tcd to the driving axles 'by "means of speed-reducing gearing. The quills or sleeves heretofore employed in such been provided {with radial arms, ,or annularjflcnges at one end only cud resilient 'or other connections have been inter osed'betwcen the same and "the l driving wieelsfand suchstructures havc quills, and t enerelly permitted of convenient assemhling of the urt's' of the rotntc ble members ls or sleeves, j Howeveq wh upon the qui large and powerful motors are tube mounted:

in this inanncr it will ener elly be found (le sirsiblc to connect bot ends of the quills to the adjacent drivin wheels', ';cnd insmother application, Serial date which both ends of the quills are provided with radial varms or flanges their mayhe re; siliently or otherwise connected toI the driving 1 wheels. l

The niegnetizcble coresof the rotetable d ynemo-clectric machines are usually end-preferably composed'of an-f; nular punchings orlmninae that are vrhounted upon supporting structures carried. the" cylinders ere he 1 no commutator quentlyv assembled upon sleeves that may also be mounted upon the supporting struc v in order to permit of reed applies,-

have shown specifically. a two-part quill structure, both parts of which nre seperable from the sup )orting StI'UCtLUQ'fOI the armsture.

The bosses are surrounded within the charmhere by resilient cushioning means, such, for exemple, as specially constructed. lrcliesl springs 8 that term the subjectmnitter of en npplicution, SerialN MZQQiALO, liledhy rue lilan uniy 8, "1906., Formed.iintogrel with or rigidly festencdto the portion =ioi the quill e spider or supporting struct J torn HiitfillPilZitlilG COX'E 10 that is composed oi" inn nuhu punchings, us is usual in mecliiues of able core, and aide at the other end of the i'naclune and the s gments of which arc assen'iblod andserurcd upon a separate sleeve 12.

in assembling the parts ol' the rotatable member, the core punchings and the sleeveu oilo the invention has been shown and described as applied to dynamo-elm:trio machines ol the direct current type, it will be iv uinlerstood that it is equally applilo alternating current machines or to machines that may he similarlv 1 l orucr ioi'nuitsd, and the details of construction and a ruug' nicnt may obviously be varied consislerably from what has been shown and deibcd without departing from the spirit of A i invention.
